Hello, I am interested in reading the number of pulses from a water meter directly through a PLC. I undestand that the water meter offers dry contact output for the pulses so I wonder if I could use a 24 V power supply and send the pulses to the PLC input, Is there any trouble with the connection that I'm trying or how could I read the pulses.
The meter I have is the model SPWM-100-CF, thanks for the support

Yes, this will work, but we recommend no more than 20mA and 24V for reading the pulse on all our water meters. So please use a resistor to limit the current, otherwise the reed switch could be damaged.

You can test the pulse output from the water meter using a continuity tester on a handheld multimeter. You should hear a beep for each rotation of the water meter dial that has a magnet on it. I would then make sure that you are limiting your amps to 20mA before connecting your PLC to the water meter pulse output.
